My understanding is that they will do the recycling themselves, on site.  They said the recycling would be mechanical, not chemical, so maybe it is just squeezing out the droww.  They also said it was an effort to be environmentally conscious, but they are in China, so I'd think it's really cost.

We are among their smaller customers, so I can't make a lot of demands.  They asked if we would accept boards made with recycled solder.  I suppose the best I can do is reply with a list of concerns and ask for test results.

Thanks!
